The influence of high pressures on structural changes of some minerals
(Elsevier Science Bv, Amsterdam, 1997)
An X-ray analysis of some of the most frequently found minerals in natural silicate soils that have previously been subjected to pressures of up to 19 GPa has been performed. The test results have shown that the increase ...
Uticaj provlažavanja tla na oštećenje objekta / Influence of the soil dampening on the structure damage
(Udruženje inženjera građevinarstva, geotehnike, arhitekture i urbanista "Izgradnja", Beograd, 2001)
Rezultati istraživanja prikazani u ovom radu pokazuju da provlažavanje podtemeljnog tla može da izazove bitne promene fizičko-mehaničkih svojstava tla. Tepromene se ogledaju u smanjenju modula stišljivosti, čvrstoće tla ...
Classification tools based on artificial neural networks for the purpose of identification of origin of organic matter and oil pollution in recent sediments
(TU Munchen, 1998)
The distinction between autochthonous, and oil-like origin of organic matter in geological sediments can be performed on the basis of n-alkane abundance and distribution patterns, determined by gas chromatography, or on ...
Identification of oil-type pollution in recent sediments
(Parlar Scientific Publications, 1997)
An attempt was made to determine the origin of soluble organic matter and to identify oil-type pollution, on the basis of n-alkane abundance and distribution patterns in the alkane fractions (determined by gas chromatography, ...
Carbonate-silica gemstone deposit Vučkovica (central Serbia) – Geologic properties, genetic processes and deposition age.
("Goce Delčev" University in Štip, Faculty of Natural and Technical Sciences, Štip, Republic of Macedonia., 2022)
Carbonate-silica veins and masses in Vučkovica locality in central Serbia, classified as Kraubath type deposit, despite their thickness, are not economically significant as magnesite deposit due to silica content well above ...
Contribution to geology and genetic pathway of the Ropočevo breccia – an "orphan" olistolithic body within the Upper Cretaceous flysch near Sopot (central Serbia)
(Published by: "Goce Delčev" University in Štip, Faculty of Natural and Technical Sciences, Štip, Republic of Macedonia, 2022)
The Ropočevo breccia, a dimension stone highly prized in 20th century, has been examined by numerous prominent geologists of the time. It is revisited by researchers still intrigued by its perplexing provenance. Its position ...
The influence of the 2020 crisis on the demand for traditional and novel construction and building materials in Serbia
(Društvo za ispitivanje i istraživanje materijala i konstrukcija Srbije, 2023)
Even though the specific COVID-19 consequences for sales have been extensively
discussed, no academic research has been done on how the pandemic has affected
consumer choice and purchases of construction and building ...
An augmented approach for the determination of the particle size effect on energy dispersive X-ray fluorescence analysis outcomes for alumina-based refractory materials
(Spectrochimica Acta Part B: Atomic Spectroscopy, 2023)
The chemical compositions of refractory materials, such as high-alumina concrete, bricks, and putty, were analyzed using an energy-dispersive X-ray spectrometer (EDXRF). An improved methodology for investigating the effect ...
Effective removal of the heavy metal ion Cd2+ from the structure of cementitious materials with mineral additives
(Structural Integrity and Life, Special Issue, 2023)
Natural zeolite and bentonite were used as mineral addi-tions to create cement-based building materials that are safe for the environment. This research focuses on the adsorptive qualities of these two clay raw materials, ...
Influence of coal ashes on fired clay brick quality: Random forest regression and artifcial neural networks modeling
(Elsevier Ltd, 2023)
Finding a solution to the problem of the large buildup of coal ashes is a vital necessity. Although the use of coal
ashes in fired clay bricks has been thoroughly investigated, there is insuffcient information on their ...
